[push] IDEA-130245 Prohibit push from detached HEAD instead of throwing exception

Create a special GitPushSource type, which never should get to the
pusher, because will be prohibited in the GitPushTargetPanel.

Support "fresh" repository case: don't allow to push as well.

Refactor GitPushTargetPanel:
  * support and display different type of "Can't push" errors.
  * detach the separator from the remote label.
